Subject: 24.4; Bug in timeclock-day-* functions (timeclock.el)
Date: Wed, 2 Mar 2016 14:51:10 -0800

Here's how to reproduce:

1. Run "emacs -Q".

2. Evaluate this:

    (load-library "timeclock.el")

3. Create some time log entries (e.g., by clocking in/out using
timeclock.el).

4. For one of the days in ~/.emacs.d/timelog, manually add the "h"
entry ("time required") to override the default required time for that
day, e.g.:

    h 2016/03/02 00:00:00 6

5. Evaluate this:

    (timeclock-reread-log)

6. Evaluate this:

    (timeclock-day-list-length (timeclock-day-alist))

      (let ((--dolist-tail-- day-list) day) (while --dolist-tail--

      (let ((length 0)) (let ((--dolist-tail-- day-list) day) (while
--dolist-tail-- (setq day (car --dolist-tail--)) (setq length (+
length (funcall func day))) (setq --dolist-tail-- (cdr

21600.0 ((22231 25979) (22231 25983) "project"))))
      timeclock-day-list-length((("2016/03/02" 21600.0 ((22231 25979)
(22231 25983) "project"))))
      eval((timeclock-day-list-length (timeclock-day-alist)) nil)
      eval-last-sexp-1(nil)
      eval-last-sexp(nil)
      call-interactively(eval-last-sexp nil nil)
      command-execute(eval-last-sexp)

Expected:  Length of day-alist from the time log, in seconds.

I think the bug is in timeclock-day-* functions which use "cdr day"
instead of "cddr day", thus failing to skip the DAY-LENGTH field of
the ENTRIES-BY-DAY alist.  When there's no "h" entry in the time log,
timeclock sets DAY-LENGTH to nil, and the timeclock-day-length
function works because it eventually executes

    timeclock-time-to-seconds (cadr nil)

which works.  But as soon as "h" is added, DAY-LENGTH becomes non-nil
which crashes timeclock as soon as it tries to take cadr of an
integer.

Note that timeclock-day-projects correctly uses cddr, unlike other
timeclock-day-* functions.

Thanks,
Oleg
